Combined Typefi friting and C011 i hlfi iiiiia TEE.

see-seen To all whom it may concern q Be it known that I, RICHARD BilQCKFL a citizen of the United States, lies Brooklyn borough, in the county i in city and State of certain new and useful lintiprovemenlzs lviachines, of Which the following is e speeilie-anon.

My invention relates to combined hype-- Writing and computing machines Que object of my invention-is the ordinary keys of a typewriter (in or machine) to be operated at any iim purpose While at the same i me the "c pe oi the typewriter are pi'e'venfied from I J lit is 3 referable in bringing" shout this result to alter the touch on the tyiewi'iter keys as little as possible. To bring aboutthis result, the keys of the typewriter may operate as ordinarily, bu; a stop is interposed which arrests the type-liars eliiioss at the printing point, yet before they come so close as "co make an impress on the pa In order to modify the haich of he typewi'iiei (in such a machine) as little as possihle, the op for arresting the pe liars is pieferahly padded, and it arrests said bars at point Where the type eam'iot trike the stop. Thus it is impossible for the type themselves to he .lDjLllTefl by striking the stop.

Other features and advantages Will hereinafter appeai'. l in the accompanying d121"ingS 'Fl,QfdTG 1 is a plan View of an Underwoodllanson combined typewriting and adding machine, showing my invent-ion as applied thereto, with most of the parts removed lies the sake of simpliciiy. 2 is a similar sectional side V'lGW. Fly. 8 is a detail of the key Whieh pi'even s the typewriter type from print ing.v Fig. 4 is a skeleton perspective View showing the connection between the y which prevents the printing and the s v which arrests (he type-hats.

In the Underwood 'typey y'ritiug machine as is usual, keys 1 on liey levers 2 swing 'oell cranks 3 so as o cause typebars 4: pivoted in a segnieiit 5 to swing upwardly ans fear- Wardly against a platen (3,-which platen is adapted to hold the Work-sheet, As said type-have approach the platen, they enter a guide 8 Which holds the type '2' against New York, have invented l' from said key lever so dial. lever is depressed said liu cram;

a he l o i is iachec a link 1! which swings a stop 18 in from? of the t pe glzide S for preventing the printing; of the type '3' on [he platen 6. Said slop is in the form of a padded l air 19 pivoted a 520 to a hug 21 screwed to the 1210111 5, and the end of said stop is pivoted ai- 22 :0 the link 17 i i suclt Way that, though the siop 18 swings no: zonlally an the hell cram: 11.8 swings yer ically "ihe nee ssa sy play will be allowed in the pivot 22. The stop 18 18 so formed that the leather 'lll "d "lll' 1 gm L Joli one sue 01 11.

As l 'lOSl easily seen in l @zwe aii'ested at such a. poim tha liot possibly throw the :=lal1e2u but yet they swing i'earw dly "e the uuiveral ha L ea? l8, as Jim in. defied lines i normally lies extending; iliag'ijoual'y Ward iroin the segment toward lhc h the machine where i lies beneath 'he but will-swing clear of such when the rihhou spools and the iy, e he; end of the segment The lever nonqizii'ntkey 33 is norm ally held upwal getting locked in ineffective position. The

, ing machine said stop in front at said typcbars so as to type-bars actuated by said and a spring norn'ially holding said step inet'l'ecti re.

5. A t vpewriting and computing machine comprising a platen and keys forming a ke v-- hoard, type-bars :wtuated by said keys for writing on said platen, a stop interposable to arrest said type-bars before the type strike the platen, a key at the keyboard for moving said stop to its eli'ective position, a spring normally holding said stop inetl eetive, and a latch operable by said key for holding said stop effective.

(5. A typewriting and computing machine con'iprising the combination with keys and a platen, of type-bars operated by said keys and comprising type for writing on said platen, a segment on which said type bars are mounted, a type-guide mounted on said segment, a stop movable between said type-- guide and said type-bars at a point mljacent said segment for arresting said type before they strike the platen, and a key for operating said stop.

7. A typewriting and computing machine. comprising the combination with keys and a platen, of ty ebars operated by said keys and comprising type for writing on said platen, a segment on which said type-bars are mounted, a type-guide mounted on said segment, a stop movable between sa'id type guide and said type-bars at a point adjacent said segment. to' arresting said type before. -they strike the platen, a spring holding said slop normally ineil'ective, and a key for moving it to eliective position. i

H. A typewriting and computing machine comprising the combination with keys and a platen, of type-bars operated by said keys and eom n'ising type for writing on said platen, a segment on which said type-bars are mounted, a type guide mounted on said segnn-nt, a stop movable between said typeguide. and said tvpe-bars at a point adjacent said segment for arresting said type bet'ore they strike the platen, a spring holding said stop normally ineil'eetive, a key for moving it to eli'ective position, and a. latch forming part of said. key for holding said stop in its etl'e tivc position.

9. A frontstrike combined typewriting and 'eompnting machine comprising the combinat ion of a, platen, typc-bars, a segment in which the. type-bars are mounted, a type guide on said segment, a stop mounted on the segment. and a key to project said stop I over the type guide in position to intercept. l the typesbars.

forwardly around a pivot 25 by which it is I attached to its key lever, so that a hook 26 forming a l-extension of its key-sten1 proper will catch under the comb 27 which serves as a guide for the key levers. when said hook l thus caught, the stop 18 is held in its eti'ective position. The key-stem of the key 18 may be prevented from swinging too far out of line by means of a stop 28 formed in an extension of said key-stem, so that said stop will lie beyond the upturned end 29 of the key lever proper and limit the-throw of said stem on said key lever. As will be best seen in Fig. 1,.the centers :20 and 22 can never get into a straight line with the link 17, and thereby the stop 18 is prevented from ever hook 26 is so formed that when it catches beneath the comb 27, it holds said comb oy its upturned end and therefore cannot be easily accidentally displaced. Said non-print key is easily released by merely pressing the top of the key rearwardly.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:

1. A typewriting and con'iputing machine comprising a key, a lever on which the key is pivoted, a comb guiding said lever, a latch forming an extension of said key adapted to lock said key in said comb, and a stop limiting the throw of said key.

2. A front-strike typewriting and computcomprising a platen and keys, type-bars for writing on said platen and operated by said keys, a segment in which said type-bars are mounted, a stop pivoted on said segment, a key for swinging arrest them as they approach the platen, and a spring normally holding said stop inetteetive.

3. A front-strike ty 'iewriting and computing machine comprising a platen and keys, type-bars actuated by said keys for writing on said platen, a segment; in which said tvpc-bars are mounted, a type-guide for alining said typediars as they a roach the platen, a stop pivoted on said segment, a key for swinging said stop across said typeguide, and a spring normally holding said stop ineti'ective. v

t. A front-strike typewriting and computing machine comprising a. platen and keys, keys for writing on said platen. a segment in which said typebars are mounted, a type-guide for alining said typel ars as they approarh the platen, a. stop pivoted on said segment, a key for swinging said stop across said type-guide,
